CURTAIN WINDOW.

Application filed April 6,

To all whom it may concern Be it known that I, Anrrronso S. CAMP- BELL, a citizen of the United States, and resident of West Medford, in the county of Mid- 'dlesex, State of Massachusetts, have invententitled ings.

ed an Improvement in Curtain Vindows, of whichthe following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements in curtain windows and this application is a continuation in part of my copending applicationSerial No. 30%,195', filed June 14, 1919, I lVindows for vehicles. It is among the objects of the invention to pro vide a curtain window of superior construction and of relatively low cost.

In the drawings, which show a preferred form of one embodiment of my invention Figure 1 is an elevation of a curtain window attached to its carrying fabric, a portion of the frame of the window being broken away;

Fig. 2 is a section, partly in elevation, of one. of the frame elements, all other parts of the installation being omitted;

3 is a sect-ion similar to Fig. 2, but shows the addition of a preferred form of filter strip cemented to the frame element illustrated in Fig. 2;

Fig. l is a section similar to Figs. 2 and 3, but shows a glass cemented to the filler strip illustrated in Fig. 3;

Fig. 5 is a section through the complete installation on the line 5 5 of Fig. 1, being partly in elevation; and i Fig. 6 is a section on the line 6-6 of Fig. 1,.being partly in elevation.

' Referring to the drawings and to the preferred form of my invention selected for illustrative purposes, I preferably provide a glasscarrying frame el ment illustrated sect-ionally in Figures 2, 3 and iof the draw- I This frame element is preferably formed of sheet metal and, as illustrated, may comprise two stamped portions, the outer or cover portion '7 and an inner or reinforcing portion 8 which may be secured in the outer portion by hanging-over the edge of the latter at 9. The inner portion 8 pref erably provides a reinforcing web '10, which is preferably turned back on itself at lL-to" stiffen the frame element, especially against 1921. Serial No. 459,117.

lateral distortion Or -bending. The inner marginal portion of the part 7 maybe flanged laterally at 12 to increase the'bea'rin'g surface thereof on the glass 13 and further to stiffen the frame against lateral distortion.- In the pocket betweenthe web'lO and the inner edge of the outer frame portion 7, I preferably provide filler means 14: which may be a strip of uncured or partially cured rubber. The filler means it is preferably cemented in the groove provided between'the web 10 and the inner portio'nof the outer frame member 7, the return flange 11 of'the web lOpre-ferably' providing a seat for the filler and allowing a recess 15 "into which the rubber maybe pressed.

The glass 13 overlies and is cemented to the filler 14, th'efianged edge 12 'of the outer frameportion preferably lying either di rectly in contact with the glass or closely adjacent thereto with a very thin film of the filler '14 interposed therebetween.

The glass-carrying frame element and the glass are, ineifect', cemented together, so that lateral distortion of the frame element which might perhaps otherwise occur is prevented by the glass, which is very strong either in tensionor under direct compres sive strains.-

The filler 14 not only-waterproofs the connection between the glass and the frame,

but providesan extended surface adapted to conform to the glass, which may vary somewhat, and is readily cementable to the glass, forminga'much stronger union than where the glass is"cementeddirectly' to the metal of the frame.

The inner portion 8 of the frame member,

hereinbefore describedymay have holes' 2O punched therethrough -and,afte'r the glass is cemented to-the flame elements! hereinbefore described, the apertured curtain fab--" ric 21 may be laid over the frame elements carrying the glass and secured thereto pref-' er'ably by self-tapping screws-22 passing through a frame-securing part 23 having'a beaded outer edge '24 and a more or less flexible inner marginal portion 25. The selfta-pping screws 22 preferably pass through therein by the self-tapping screws, while the apertures in the inner frame element-8 apertures in 'the securing element 23 0f snfinto which the self-tapping screws passfare preferably of a diameter such that the self tapping screws will cut threads therein. If the apertures in the inner frame element 8 are broken through rather than punched through, a certain amount of the metal will be projected inwardly to provide a longer surface in which threads may be cut by the self-tapping screws, all as is best illustrated in Fig. 5 of the drawings. The curtain fabric need not be perforated for passage therethrough of the self-tapping screws, which are ordinarily, as illustrated, pointed on their ends and which separate without substantial cutting the threads of the curtain fabric.

The securing element 23 and the self-tapping screws are concealed by a cover 30 which is adapted to spring over the bead. 24: so that the underlying lip 31 may securely hold the cover element 30 in place with its inner edge 32 which is, as illustrated, prefeably flanged to provide an extended lip bearing against the glass 13. As the self tapping screws are drawn up, the filler strip 14: will be pressed into its recess and the glass will be strongly pressed against the outer face of the filler strip so that, when the cement connecting these parts together dries, great strength will be imparted to the frame as a whole, not only the frame element carrying the glass being reinforced by the glass itself, but the frame elements lying on the opposite side of the glass being preferably, as illustrated, similarly reinforced by reason of their being secured to the glass-carrying frame element.

A construction along the lines illustrated and described is of great advantage in connection with the manufacture of curtain windows of any size and shape, but is particularly advantageous in connection with relatively large curtain windows in which the problem of stiffening the frames to prevent lateral flening thereof away from the glass is one which does not have to be overcome to any great extent in connection with relatively small curtain windows, and es pecially in connection. with relatively small. curtain windows in which the frames are round or oval so that the strength of the material is enhanced by reason of its arched shape.

While I have shown and described a preferred form. of one embodiment of my invention, it will be understood that changes involving ommission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

Claims:

1. A curtain window installation comprising, in combination, a flexible frame scoured to the curtain and normally subjected to distorting stresses tending to separate the upper and lower portions thereof, said frame having a glass receiving portion, a glass in said glass receiving portion, and distortion resisting filler means interposed between a portion of said frame and glass to insure a more perfect bond, said glass being securely cemented to said filler means and constituting a reinforcing element whereby to prevent distortions of the frame in the plane of the glass.

2. A curtain window installation comprising, in combination, a flexible frame secured to the curtain and normally subjected to distorting stresses tending to separate the upper and lower portions thereof, said frame having a glass receiving portion, a glass in said glass receiving portion, and distortion resisting filler means interposed between a portion of said frame and glass to insure a more perfect bond, said glass being securely cemented to said. filler means and constituting a reinforcing element whereby to prevent distortions of the frame in the plane of the glass, said frame present ing a relatively narrow edge adjacent one face of the glass and a recess behind said edge into which said filler means extends to strengthen the bond between said filler means and said frame under the strain of said distorting stresses.
